Actual off road capability of composite campers.

It all comes down to engineering and knowledge. Unicat was at the forefront and working closely with Mercedes.

What wheels and tires are on your truck? Can you compare the highway ride to a 1ton with factory singles and a lighter camper?

I hear a lot that super single setups are hard to get the tires balanced so there isn't added vibration at highway speeds.

The truck came with super singles and Hutchinson rims. Everything about that setup is garbage. Took both ball joints out in 40,000mi (on a 5500!). Never balanced properly. Front tires cup badly. Almost nobody will deal with the "split rims". Tires are at least 600USD each. Good ones are 1000+. They are very hard to find and ship. Etc etc etc. The rig is now on a decent set of dualies and everything is much better.

We usually pucker up and freak out when we get about half way to the tipping point. Because he's bouncing, he's probably over half way.

To clarify, in a static situation the CG needs to tilt past the tire contact point that you'll be pivoting on when you tip over. For instance, say his CG is in the center of his rig, and at the level of the top of the radiator where you drew the line. If you draw a vertical line through the tire contact with the ground, he's still a long way from that point. And his actual CG is probably quite a bit lower.

This ^^... It may 'feel' like it's going to tip, but you are likely a very long way away from that happening.

I have flopped my 1985 Toyota 4Runner over on its side once and was a passenger in a Toyota truggy and a Jeep truggy, both on 39" tires when each of them rolled completely and came to rest on their roof/roll cage.

So, unless you have done something really dumb, or participated in serious rock crawling, you've probably never approached the limits of your vehicle. Now, with lifted vans and gigantic expo rigs being the rage these days, I would still urge caution, but it takes a lot to flop a truck.
